Instructions
Cook the spaghetti
Bring a large pot of salted water to a boil. Add spaghetti and cook until al dente, about 8-10 minutes. Reserve 1/2 cup of pasta water, then drain.
Pro tip: Do not rinse the pasta; the starch helps the sauce adhere.
Prepare the onion
In a large pan, heat olive oil over medium heat. Add the chopped onion and sauté until soft and translucent, about 5 minutes.
Pro tip: Stir frequently to avoid browning.
Add the garlic
Add minced garlic to the pan and sauté for an additional 1-2 minutes until fragrant.
Pro tip: Be careful not to burn the garlic.
Make the sauce
Reduce heat to low. Stir in heavy cream and bring to a gentle simmer.
Pro tip: Do not let the cream boil.
Incorporate the cheese
Add the grated Parmesan cheese to the sauce, stirring until melted and smooth.
Pro tip: Use freshly grated cheese for the best flavour.
Finish the dish
Add cooked spaghetti to the sauce. Toss to combine, adding reserved pasta water as needed to reach desired consistency. Season with salt and pepper.
Pro tip: Top with extra Parmesan and parsley if desired.
Tips & Tricks
